The article dwells on the issues beset with the comparative analysis of morphological peculiarities and the level of usage of the nominal suffix -zor in the Tajik literary language referring to 18^th and 20^th centuries on the example of the historical writings [2; 3; 13]. It is noted that the relevant suffix is one of the oldest and rarely used word-building elements in the language of the compared historical writings, like MTLL.
It is concluded that the suffix -zor participates to the formation of series of derivative words denoting the notions of place and plenty, but the level of their usage is not identical. It is proven that the word korzor is used only as an underived one in “Tuhfat-ul-khoni”. One of the distinctive peculiarities of the nouns derived by dint of the suffix -zor lies in the fact that they are plurified by the suffix -ho only in ustod Aini’s works.
